only caveat with power ladders...you will need time. I do ladders with squats in the 80-85% range, I need a lot of time to get through it..One thing I have considered, you might think about it as well, alternate between several weeks of power ladders and couple weeks of density work or a general hypertrophy, limited rest progression~ anything that will boost your work capacity on the movement.... better long term progress, safer and avoid burnout.
